If the ratio of red hair bands to green hair bands is 5 to 9 with a total of 70 hair bands, how many of them are green?
5/14 = x/70
Cross multiply and solve for x.
i dont understand this
so the answer is 14 ms sue
another way
multiply both sidees of this equation by the least common multiple of 14 and 70
I think 140 is close enough
140(5/14) = 140(x/70)
10 * 5 = 2 * x
5 * 5 = x
25 = x
There are 14 hair bands all together.

now try that
25/70 = ?
5/14 whew !!!
but I think you wanted GREEN
(9/14) (70) = 45
